If you would like to have a leg up in your next water balloon fight (and who wouldn’t?), then this ingenious device, the Tie-Knot Water Balloon Filler, is just what you need to stockpile your liquid-y ammo quickly and easily. There is a four step method to filling and tying each balloon and the demonstration video from ThinkGeek makes the entire process look quick simple.
This little gadget for summertime fun was developed by the Illinois wholesale company, Tie-Not, and is manufactured entirely in the United States.
